LL_RTC_TIME_SetSecond
Function name
__STATIC_INLINE void LL_RTC_TIME_SetSecond
(RTC_TypeDef * RTCx, uint32_t Seconds)
Function description
Set Seconds in BCD format.
Parameters
RTCx: RTC Instance
Seconds: Value between Min_Data=0x00 and
Max_Data=0x59
Return values
None:
Notes
Bit is write-protected. LL_RTC_DisableWriteProtection
function should be called before.
It can be written in initialization mode only
(LL_RTC_EnableInitMode function)
helper macro __LL_RTC_CONVERT_BIN2BCD is available
to convert Seconds from binary to BCD format

LL_RTC_TIME_GetSecond
Function name
__STATIC_INLINE uint32_t LL_RTC_TIME_GetSecond

Function description
Get Seconds in BCD format.
Parameters
RTCx: RTC Instance
Return values
Value: between Min_Data=0x00 and Max_Data=0x59
Notes
if shadow mode is disabled (BYPSHAD=0), need to check if
RSF flag is set before reading this bit
Read either RTC_SSR or RTC_TR locks the values in the
higher-order calendar shadow registers until RTC_DR is read
(LL_RTC_ReadReg(RTC, DR)).

Minutes, uint32_t Seconds)
Function description
Set time (hour, minute and second) in BCD format.
